Recent Advances in Electrochemical Analytical Methods Involving Metal Enolates

Abstract

The chapter is an update of one published in 2009, covering the literature up to the autumn of 2014. Due to space limitations assigned to chapters in this book, the review of analytical methods was divided into two parts, the present chapter dealing with electrochemical methods of analysis, especially modified electrodes, and its companion dealing with all the rest. The same guidelines as in the older chapter were followed for the selection of analytical methods, namely: detection and determination of specific metal enolates, conversion of metal cation analytes into complexes with enolic ligands before end analysis and the use of certain metal enolates as analytical aids and tools.

Control of Al composition of mist chemical vapor deposition grown α-(AlGa)2O3 alloy thin films by acetylacetonation of Al ion

“…It is known that Hacac takes both enol and keto forms, and an acac ligand coordinates to a metal ion in the enol form. 36) When adding Hacac to the AlCl 3 aqueous solution and stirring, clear dips of the enol form produced by complexation at 1395 and 1535 cm −1 appeared. 37) As the stirring time increased, the dips indicating the enol form became deeper.…”

Palladium-mediated CO2 extrusion followed by insertion of ketenes: translating mechanistic studies to develop a one-pot method for the synthesis of ketones

“…Here, we turn our attention to a new ExIn variant involving decarboxylation followed by insertion of a ketene (for the chemistry of ketenes, see refs [34][35][36] ) to form a coordinated enolate, [37] which then reacts to form a ketone (for examples of metal-mediated ketone synthesis using other organic substrates, see refs [38 ,39] ). We note that insertion of ketenes into Pd-C bonds has been reported [40,41] and that there is a rich literature on palladium enolates (e.g.…”
